132 / 1071 page ![]() Section 1 Overview Rev. 5.00 Aug 08, 2006 page 46 of 982 REJ09B0054-0500 Pin No. Type Symbol TFP-100B TFP-100BV FP-100B FP-100BV FP-100A FP-100AV I/O Function Data bus D15 to D0 100 to 96, 11 to 1 100, 99, 14 to 1 Input/ output Used as the bidirectional data bus. Bus control CS7 CS6 CS5 CS4 CS3 CS2 CS1 CS0 87 88 89 90 92 93 94 95 90 91 92 93 95 96 97 98 Output Select signals for areas 7 to 0. AS 69 72 Output When this pin is low, it indicates valid address output on the address bus. RD 70 73 Output When this pin is low, it indicates that the external address space is being read. HWR 71 74 Output Strobe signal: Writes to the external address bus to indicate valid data on the upper data bus (D15 to D8). LWR 72 75 Output Strobe signal: Writes to the external bus to indicate valid data on the lower data bus (D7 to D0). WAIT 73 76 Input Requests insertion of wait states in bus cycle when accesses to the external three- state address. 16-bit timer- pulse unit (TPU) TCLKD TCLKC TCLKB TCLKA 41 39 37 36 44 42 40 39 Input These pins input an external clock. TIOCA0 TIOCB0 TIOCC0 TIOCD0 34 35 36 37 37 38 39 40 Input/ Output Pins for the TGRA_0 to TGRD_0 input capture input, output compare output, or PWM output. TIOCA1 TIOCB1 38 39 41 42 Input/ Output Pins for the TGRA _1 and TGRB_1 input capture input, output compare output, or PWM output. TIOCA2 TIOCB2 40 41 43 44 Input/ Output Pins for the TGRA _2 and TGRB_2 input capture input, output compare output, or PWM output. |
